They charge you extra fees for a carry on bag if the people decides it! I flight with the same airline from mx city to denver and they charged nothing while from denver to mx city they charged 25 dollars with the same suitcase! Also delta gives you free basic wifi while this guys charge it extra. Btw they take away all your carry ons amd make you to wait for hours to get them back! They dont have automatized check in so they make you wait for long time in the row.

Seats were comfortable, even in economy. Personal entertainment at each seat with a good selection of movies and easy way to navigate to English language. The flight attendants were very nice, and they provided not only drinks but also a full snack tray to each person. Flight was right on time and announcement were in Spanish and English which was important for me as I don't speak Spanish..

The waiting area at the Boston airport is poor. It is very small, rundown and with limited access to refreshments. It's ok but certainly not a selling point.

I like that they are Canadian

I don't like how unhelpful they are, their food, their staff, the way they treat clients etc. Seriously my least favourite company to fly with. I'd rather pay extra and fly WestJet anyday!

Normally, getting on a plane in Colombia is an absolute nightmare. People pushing, standing right next to you, when you get on the plane all the old women who do not know how to read always walk to the back of the plane when they're supposed to be sitting in seat 7? Been there? Seen that? Yes ! Seen it a million times. What makes this particular flight so unbelievable, and maybe it was just a training day because there was a lot of airline personnel at the check in kiosk, but I have never processed on to a flight in Columbia, given up my baggage, and be walking to the gate so fast in my life! I truly hope this is something that will become standard, and I pray to God that the other airlines especially Viva will learn how to do!

Overall very good, good crew... minus point.. seats SO tiny, it makes Asian airline economy seats feel like 1st class!

My flight to Lima was delayed therefore I would miss the connecting flight to LAX. I learned of the delay by overhearing a conversation the employee was having with another passenger. No announcement was made, no options were presented to help the passengers with connection find a solution until we started demanding a solution. This ordeal started at 9pm and we did not make it out of the airport till 1:50am to a hotel for a 6am pickup back to the airport to start the process all over again.

Nothing, it was by far the worst fly experience I've ever had.

I did not like everything: a) 24 hours of delay. We were suppose to fly from Buenos Aires to Paris through Sao Paulo. Instead of flying to Sao Paulo they went to Rio de Janeiro. The excuse was that "there are too many planes in the airport and we don't have enough fuel to wait in the air". Very encouraging! In case of emergency they have enough fuel for let's say 30 additional minutes. b) Once we arrive to Rio, instead of letting us fly to our final destinations from there (yes, there were many, many flights from there) they decided to let us wait 3 hours with all the uncertainty and of course no food (2 AM in the morning). We finally flew back to Sao Paulo. No one from LATAM was there, so we literally didn't know what to do. The police came after 40 minutes and they finally called LATAM. c) They lost my luggage. LAN and TAM used to be quite good. LATAM is just too bad.

Very unfriendly and difficult process to select seats. Impossible and almost unfriendly personnel, process to attempt to buy upgrade to. Haines even though 1/2 seats available. What a shame for an otherwise good experience.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
